You took four snapshots of some geometric shapes that you saw on your train trip around a circular track. You dropped the pictures and got them mixed up, and now you must imagine your trip to put them back in order.
Study inscribed angles in semicircles and quarter-circles. What conjectures can you make about the measure of an inscribed angle in semi- or quarter-circles?
Read a story and draw a graph that tells the same story. Next look at a graph and write a story to match.
Visit an amusement park and try to solve six conversion problems as fast as you can.
Observe as a sheet of letter-sized paper is cut and assembled to form a rectangular prism, a triangular prism and a cylinder. Which object would contain the greatest volume?
Did you know that there are other temperature scales besides Fahrenheit and Celsius? Read the descriptions of all the scales and then match the scale to the correct thermometer.
Study the names and abbreviations of length units in both the metric and British systems. Then play a game to see how well you remember them.
A limerick is a very funny piece of nonsense verse with its own special pattern of rhyme and rhythm. Use this tool to choose phrases to create your own limerick that follows the pattern.
Create line plots that have a mean of 5 but different deviations from the mean. Notice that the total deviation above the mean must equal the total deviation below the mean.
Consider two graphs representing the number of people present at two different locations over the course of the day. Interpret the graphs to guess the locations.
Practice creating a line plot. Use raisin counts for 17 boxes of raisins to graph the distribution of raisins per box.
A line plot may not be a useful graph for investigating variation so we must come up with a new representation based on groups of data. Construct a stem and leaf plot from a set of 26 data values.
A tree diagram is a helpful tool for determining theoretical or mathematical probabilities. Toss a coin and watch as branches represent a toss of either head or tails.
Study the names and abbreviations of mass units in both the metric and British systems. Then play a game to see how well you remember them.
Compare your recall of a list of non-words versus a list of words in timed sessions. Consider whether or not there might be bias in your experimental design.
Does the ratio of height to distance and the angle of elevation change as you move a ladder? Identify any patterns that exist between the height-to-distance ratios and the angles.
Determine the median of eleven noodles. Consider what you would or would not be able to tell about the other noodles if you could only see the median noodle.
You can cut geometric figures into pieces that you can rearrange to form different geometric figures. Show how the midline cut of any triangle can be used to form a parallelogram.
Use the slider on the graph to see all possible shapes of Ms. Anwar’s 2,000 sq. ft. backyard. Come up with an equation relating the length (x) and the width (y).
Area models can be used for many types of multiplication problems. Work with manipulatives to create area models for some multi-digit multiplication.
